5,5-Diphenylhydantoin Usage And Synthesis
Chemical Propertieswhite crystals or powder
UsesReduces incidence of grand mal seizures; appears to stabilize excitable membranes perhaps through effects on Na+, K+, and Ca2+ channels.
UsesA sodium channel protein inhibitor
DefinitionChEBI: A imidazolidine-2,4-dione that consists of hydantoin bearing two phenyl substituents at position 5.
Brand nameAnticonvulsant. Dilantin (Pfizer) [Name previously used: Diphenylhydantoin.].
General DescriptionFine white or almost white crystalline powder. Odorless or almost odorless. Tasteless.
Air & Water ReactionsInsoluble in water.
Reactivity Profile5,5-Diphenylhydantoin is an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). 5,5-Diphenylhydantoin is incompatible with strong oxidizers and strong bases.
Fire HazardFlash point data for 5,5-Diphenylhydantoin are not available; however, 5,5-Diphenylhydantoin is probably combustible.
Purification MethodsCrystallise the hydantoin from EtOH. [Beilstein 24 III/IV 1748.]
